To solve: the system of linear equation.
Answer to Problem 13E
All of the equalities are true; the ordered pair
Explanation of Solution
Given:
Calculation:
Since both expressions
Set them equal to each other forming an equation in x
Move variable x to the left side and change its sign
Collect like terms
Divide both sides by -2
Substitute the value of x into the equation
Solve the equation for y
The possible solution of the system is the ordered pair
Check if the given ordered pair is the solution of the system of equations
Simplify the equalities
Since all of the equalities are true, the ordered pair
Conclusion:
Therefore, all of the equalities are true; the ordered pair
